Method and reactor for producing hydrogen sulphide

摘要

Reactor suitable for continuous preparation of hydrogen sulfide by exothermic reaction of sulfur and hydrogen to form a final product gas mixture P f i n a l comprising hydrogen sulfide and sulfur at elevated temperature and elevated pressure relative to standard conditions, comprises a lower reactor region suitable for accommodating a sulfur melt, and a gas collecting region suitable for accommodating the product gas mixture P f i n a l at elevated temperature and elevated pressure relative to standard conditions. Reactor suitable for continuous preparation of hydrogen sulfide by exothermic reaction of sulfur and hydrogen to form a final product gas mixture P f i n a l comprising hydrogen sulfide and sulfur at elevated temperature and elevated pressure relative to standard conditions, comprises a lower reactor region suitable for accommodating a sulfur melt, and a gas collecting region suitable for accommodating the product gas mixture P f i n a l at elevated temperature and elevated pressure relative to standard conditions, where the reactor comprises at least two non-pressure-bearing first caverns and at least one supply device suitable for controlled supply of pressurized gaseous hydrogen per first cavern, the caverns being suitable for at least temporary accommodation of a product gas mixture P 1 which forms in exothermic reaction and comprises hydrogen sulfide, sulfur and hydrogen. An independent claim is included for process for preparing hydrogen sulfide by exothermic reaction of sulfur with hydrogen at elevated temperature and elevated pressure relative to standard conditions to form a product gas mixture P f i n a l comprising hydrogen sulfide and sulfur, involving providing a sulfur melt in a lower reactor region of a pressurized reactor, supplying pressurized hydrogen into the sulfur melt, the hydrogen supplied being accommodated at least partly, together with sulfur converted from the sulfur melt to the gaseous state, by at least two non-pressure-bearing first caverns, at least temporarily leaving the hydrogen and the sulfur in the first caverns, so as to form, in exothermic reaction, a product gas mixture P 1 comprising hydrogen sulfide, sulfur and hydrogen, and collecting the product gas mixture P f i n a l in a gas collecting region.
